THE ORCHID REVIEW. 149 
On watering days (Wednesdays and Saturdays), and at other times if 
required, we turn the heat on the tank early in the morning, and in summer 
immediately the temperature is at 66° or 68° the valve is turned off. 
During the winter months 62° or 63° is sufficient. With water at. these 
temperatures the whole of the inmates of the East Indian house are 
supplied. For the Cattleyas and other Intermediate house. plants the 
temperature is reduced by several degrees, and of course colder water is 
used for Odontoglossums, Masdevallias, and all other cool-growing Orchids. 
With regard to syringing much may be said both for and against the 
practice. ‘If it be done indiscriminately and without care, evil results will 
follow. Never syringe a plant that is suspended above others, or the water 
will drip into the growths of those underneath, and if not immediately 
removed many valuable plants may be ruined. Where the syringe is used 
with discretion some Orchids appreciate the operation immensely. When 
in full growth, such plants as Dendrobiums, Sobralias, Lelia anceps, Vanda 
teres, and many of the Cypripediums delight in a gentle sprinkling overhead 
early on a warm summer afternoon, but such Cypripediums as Lowil, 
Stonei, philippinense, and Selenipedium caudatum should not be syringed 
overhead, as the water will probably remain in the centre of the growths, 
causing decay and the loss of many leaves. Cypripediums should never be 
allowed to become dry at the root and should receive a thorough soaking as 
often as necessary. Cattleyas and Lezlias of the elegans type require very 
careful watering, even during the growing season. It is frequently and 
easily overdone, especially when the plants are not properly potted. The 
majority of our Cattleyas receive a good watering about once a week, but 
less often in the case of those that are in large pots and have more material 
about their roots, while to those in small pots, and well rooted, water is 
given more frequently. -Pleiones, Sobralias, Stanhopeas, Coelogynes, 
Zygopetalums, and the tall-growing Epidendrums, should be watered 
frequently, and they will appreciate a soaking of weak liquid cow-manure 
once a week during the summer months. The cooler growing plants must 
be watered often enough to keep the sphagnum moss growing. Plants on 
blocks require much attention, and should be watered at least once a day 
during growth. As the young roots of Aérides are now in full activity, the 
amount of moisture both at the root and in the atmosphere must be largely 
increased. Damp down between the pots both morning and afternoon, 
using tepid rain-water in preference to any other, and as the plants 
Té-establish themselves, more light may be given, by drawing up the 
blinds a little earlier in the afternoon than usual. This will prevent the 
Stowths from becoming drawn, and help to harden the plants, so that they 
may pass through their resting season without any great loss of foliage. 
The Phalenopses may now be taken in hand. Those phat eres SHOre 
Toot room should receive it at once, or if the material in which they are
